Not sure about 4x10 but PJB makes an excellent sounding and quality cabinet called the 12B that has removable casters. The casters are very well built and are the larger rubber type that lock. I've got one and I love the sound. Below is the link. But then again a trip to Home Depot or Lowes and for very little money one can buy and install a set of casters very easily.

GK and Carvins also has casters on their 410's. But like Bassguy1 said, and as I did, I went to Lowes and got a 4 removable casters and installed them myself. The bigger the rubber wheels are the better.
